Question

The volume of the cube whose edge is $\text{3x}$ is

• A. ${\text{27x}}^3$
• B. $9{\text{x}}^3$
• C. $6{\text{x}}^3$
• D. $3{\text{x}}^3$

Answer 1

The correct option is A

${\text{27x}}^3$

We know that volume of the cube is $={\text{(side)}}^3$

Here side or edge is given $=3\text{x}$

So volume of cube is $=(3{\text{x)}}^3{\text{=27x}}^3$

Hence option(A) is the correct answer and all other options are incorrect answers .
